You should definitely try reaching out to Nvidia support since they wrote the OS image. Reference this forum thread and offer as much info as possible
I suspect the issue could be with the router. I had a hell of time getting a stable connection with the n150 edimax when i tried at home on my tp-link wr841n router. Interestingly, the connection was very stable with low latency response when i took it to work. I dont know the exact router in the office, but it works anytime i take it to office but gets unstable at home. I will update on the office router type.
I just received the SparkFun JetBot Nano kit and have been having very similar issues.
Like the poster here, I also thought this was due to a faulty WiFi adapter.
But now, I think that this behavior is related to power management on the Linux side. I ran across this post https://askubuntu.com/a/707132. And there is a linked post here: https://www.raspberrypi.org/forums/view … hp?t=61665. Although these are technically for a different version of the WiFi adapter, I think the premise is the same.
Running lsmod I surmised the controller/driver name is ‘8732bu’.
So on the device, I created a file:
/etc/modprobe.d/8732bu.conf
and added the contents:
options 8732bu rtw_power_mgnt=0 rtw_enusbss=0
I also ran this on the device but I’m not sure this helped sudo iw dev wlan0 set power_save off.
Then I rebooted and turned WiFi on and off in the Ubuntu UI. Then I was finally able to play with the Jetbot Nano!
Before this, the Jetbot would disconnect from the WiFi after a few seconds. Then it would be pretty tough to get the WiFi back connected. I think just turning off and turning the WiFi back on seems to work now. I’m doing this on the Ubuntu UI.
I ran into this link https://www.digikey.com/en/maker/projec … 81b80b8ec2 which mentions that you can update a /etc/modeprobe.d/blacklist.conf which might give similar results.
So it’s a bit clunky getting it to connect to WiFi but hopefully this will help someone get the WiFi connected. Also, I did realize that the IP address / or No Internet Connection that shows on OLED is not always accurate. There can be no internet connection when the LED shows internet connection; also I’ve been connected to the internet and had the OLED say “No Internet Connection!”.
So for me, adding the power management options options 8732bu rtw_power_mgnt=0 rtw_enusbss=0 to /etc/modprobe.d/8732bu.conf appear to have helped resolve this issue. Although, I’ve just tested it a little at this point. Pretty fun to get the thing running for the first time!
Dear all, I am facing the very similar issue with the exact same behaviour observed by others on this post.
I tried most of the things mentioned here but issue is still unresolved. Kindly update if anyone could resolve this. I am going to try few things from power management side, will update here if it is resolved. Thanks!
